Device Control
Advanced users can control the transmitter via API commands through
UPDATE port on transmitter or RS232 port on receiver: connect a control PC
or control system to the UPDATE port of the transmitter (see Figure 1) or the
RS232 port of the receiver (see Figure 2). API command for device control is
available in the separate document. A professional RS232 serial interface
software (e.g. Serial Assist) may be needed as well.
Before sending the API command to control the transmitter, ensure the
transmitter, control PC and/or receiver are configured correctly.
